I have also posted this in the pets section to get more responses.
My dog is around 13.5 and has always been in good health.
She has recently developed a problem with her feet whereby the nails peel off very slowly over the course of a week or more, leaving just the bleeding quick behind 
Over 50% of the nails have now fallen off, and most of the rest are loose.
This condition causes her immense pain. She is on constant painkillers, but whenever she has a loose claw she is unable t go upstairs, walk on bumpy ground etc. Bearing in mind she always has one, if not two or three loose claws, this causes her a few problems.
Although she will have some respite when the new claws grow back, it is highly likely the new ones will peel off too.
The vet has asked me to think about whether it would be kinder to anaesthetise the dog and remove all of her claws so she can gain some mobility again and put her out of constant pain.
However I can't help but think that even though she is otherwise fit, happy and healthy, that she might die on the table :( DH thinks I am being irrational, which I probably am, but I really don't know what to do.
What would you do in this situation?
